Summary Background High weight gain in pregnancy has been associated with child adiposity, but few studies have assessed the relationship across childhood or in racially/ethnically diverse populations. Objectives The objectives of the study are to test if weight gain in pregnancy is associated with high birthweight and overweight/obesity in early, middle and late childhood and whether these associations differ by maternal race/ethnicity. Methods Mother‐child dyads (n = 7539) were included from the National Longitudinal Survey of Youth 1979, a nationally representative cohort study in the USA (1979–2012). Log‐binomial regression models were used to analyse associations between weight gain and the outcomes: high birthweight (>4000 g) and overweight/obesity at ages 2–5, 6–11 and 12–19 years. Results Excessive weight gain was positively associated, and inadequate weight gain was negatively associated with high birthweight after confounder adjustment ( P < 0.05). Only excessive weight gain was associated with overweight in early, middle and late childhood. These associations were not significant in Hispanics or Blacks although racial/ethnic interaction was only significant ages 12–19 years ( P = 0.03). Conclusions Helping pregnant women gain weight within national recommendations may aid in preventing overweight and obesity across childhood, particularly for non‐Hispanic White mothers.
